Our architects have conducted detailed shadow studies to ensure the development maximises solar access. The proposal ensures a minimum of 50% direct sunlight to the main usable part of communal open space for at least 2 hours between 9 am and 3 pm on the shortest day of the year. Properties to the west of the site remain unobstructed after 11 am, minimising overshadowing effects.

We are seeking an additional 30% height uplift (7 levels) in line with the NSW Government's State Environmental Planning Policy (Housing) 2021. The policy, aimed at enhancing housing supply, diversity and affordability in strategic areas, allows for such height increases when a minimum of 15% of GFA is allocated to affordable housing. The increased height will allow for the provision of affordable housing apartments and reflects our commitment to expand housing supply in key areas.

Our approach to mitigating construction impacts include the preparation of a Construction Traffic Management Plan (CTMP) outlining measures to manage traffic flow and pedestrian safety, a Noise and Vibration Impact Assessment (NVIA) ensuring compliance with standards and guidelines, and Geotechnical reports addressing structural vibrations and other construction-related issues. Regular noise monitoring and implementation of recommended measures during both construction and operational phases will be undertaken to minimise disruptions during the project's construction phase.

With vehicle access facilitated through a single driveway allowing two-way traffic movement into the basement levels, the streetscape impact will be minimised. Additionally, the provision of parking spaces will strike a balance between meeting the needs of future residents and supporting public and active transport, aligning with the Chatswood CBD Strategy. A Traffic Impact Assessment is also being prepared to accompany the development submission, ensuring thorough evaluation and mitigation of any potential traffic concerns.

Windtech (consulting engineers specialising in the analysis of wind effects on various structures, buildings, and the environment) have been engaged to assess the local wind environment at critical outdoor areas within and around the subject site. Their report will recommend various mitigation measures to reduce wind within the development, such as retention of trees, physical obstruction and screens etc. Earlier analysis conducted for the previous DA found the western laneway already benefits from shielding from surrounding buildings and tree planting.
